Abstract

A paper sheet package (9) capable of storing thermosensible paper in a box-like body (8) formed of a paper material, wherein the arrangement direction (direction of arrows B) of the paper fibers of the thermosensible paper (7) is generally same as the arrangement direction (direction of arrows C) of the paper fibers of an upper wall part (8h), a cover part (8c), and a tongue part (8e) since the arrangement directions of the paper fibers of the thermosensible paper (7) and the upper wall part (8h), cover part (8c), and tongue part (8e) of the body (8d) of the box-like body (8) makes it hard for the paper and these parts to be affected by moisture to reduce the degree of swelling so as to make equal the swelling characteristics thereof to each other.

Description

明細書 用紙パッケージ 技術分野  Description Paper Package Technical Field
本発明は、 プリン夕等に使用される用紙を積層した状態で収納する箱状体を有 する用紙パッケージに関する。 背景技術  The present invention relates to a paper package having a box-shaped body for storing paper used for a pudding or the like in a stacked state. Background art
従来より、 用紙を積層した状態で収納する箱状に形成された、 所謂、 用紙カセ ッ トが種々知られている。 かかる用紙カセッ トは、 用紙を積層状態で収納したま まプリンタ等にセッ トされて使用されるものであり、 用紙カセッ トからはプリン タ等に配設された用紙送り機構を介して用紙が一枚ずつ印字機構に送り出される ように構成されている。  2. Description of the Related Art Conventionally, various so-called paper cassettes formed in a box shape for storing paper in a stacked state have been known. Such a paper cassette is used by being set in a printer or the like while storing the paper in a stacked state, and the paper is fed from the paper cassette via a paper feed mechanism provided in the printer or the like. It is configured to be sent out to the printing mechanism one sheet at a time.
前記用紙カセッ トは、 用紙を積層状態で収納する箱状体を有しており、 この箱 状体は金属、 プラスチック等の材料から形成されているのが一般的である。 金属 やプラスチックは、 湿度による影響を殆ど受けることがなく、 その膨潤特性につ いては無視できる程度である。 一方、 箱状体内に収納される用紙は、 金属、 ブラ スチックと比較して、 湿度により大きな影響を受け、 その膨潤特性は無視できな レ^ プリンタ等に使用される用紙には、 その紙繊維の方向がランダムに構成され てものも存在するが、 用紙における紙繊維の方向は一方向に配列されているのが 一般的である。 このように紙繊維が一方向に配列されている用紙においては、 紙 繊維が配列されている方向 （紙繊維の方向） には湿度の影響を受け難く膨潤の程 度は小さいが、 紙繊維の方向と直交する方向には湿度の影響を受け易く膨潤の程 度は大きいという傾向がある。  The paper cassette has a box-shaped body for storing sheets in a stacked state, and this box-shaped body is generally formed of a material such as metal or plastic. Metals and plastics are hardly affected by humidity and have negligible swelling properties. On the other hand, paper stored in a box is more affected by humidity than metal and plastic, and its swelling characteristics cannot be ignored. Although the direction of the paper fibers may be randomly arranged, the direction of the paper fibers in the paper is generally arranged in one direction. Thus, in the paper in which the paper fibers are arranged in one direction, the direction in which the paper fibers are arranged (the direction of the paper fibers) is hardly affected by humidity and the degree of swelling is small, In the direction perpendicular to the direction, there is a tendency that the degree of swelling is large due to the influence of humidity.
前記した箱状体が金属やプラスチックで形成された用紙カセッ トにおいては、 箱状体における湿度に対する膨潤特性については無視できるので、 プリン夕等が 使用される環境を考慮して想定される湿度範囲における用紙の膨潤特性だけを勘 案すればよく、 従って、 用紙の両側端縁と箱状体の側壁内面との間で発生する摩 擦力を比較的容易に設定できることから、 用紙カセッ ト内の用紙は、 プリンタ等 の用紙送り機構を介して、 比較的安定して送り出すことが可能である。 発明の開示 In a paper cassette in which the box is made of metal or plastic, the swelling characteristics of the box with respect to humidity are negligible, so the humidity range assumed in consideration of the environment in which the printer is used is considered. Only the swelling characteristics of the paper at the time need be taken into account, and therefore, the friction generated between the side edges of the paper and the inner surface of the side wall of the box-shaped body is required. Since the frictional force can be set relatively easily, the paper in the paper cassette can be relatively stably fed out through a paper feed mechanism such as a printer. Disclosure of the invention
簡易パッケージングが推奨されている現今においては、 金属やプラスチックか ら形成された用紙カセッ 卜に代えて、 紙材から形成した用紙パッケージ内に用紙 を積層状態で収納し、 かかる用紙パッケージをそのままプリン夕等にセッ 卜して 使用する形態が提案されつつある。  At present, when simple packaging is recommended, instead of a paper cassette made of metal or plastic, paper is stored in a stacked state in a paper package made of paper material, and the paper package is printed as it is. It is being proposed to use it in the evening.
かかる用紙パッケージは、 その内部に収納される用紙と同様、 パッケージが紙 材から形成されているので、湿度により大きな影響を受けることとなる。従って、 湿度の影響に起因する用紙の膨潤程度と用紙パッケージの膨潤程度の双方を十分 把握して用紙パッケージの設計を行わないと、 種々の問題が発生する。  Such a paper package is greatly affected by humidity because the package is formed of paper material, similarly to the paper stored in the paper package. Therefore, various problems occur unless the paper package is designed with sufficient understanding of both the degree of swelling of the paper and the degree of swelling of the paper package caused by the influence of humidity.
例えば、 用紙の膨潤程度が用紙パッケージの膨潤程度よりも大きい場合には、 用紙の両側端縁が用紙パッケージにおける箱状体の側壁内面に対して強く接触す る。 この場合、 両者間の摩擦力が必要以上に大きくなり、 この結果、 プリ ンタ等 の紙送り機構による紙送り時に用紙が送り出されなくなって空送を発生してしま うという問題がある。 また、 用紙の膨潤程度が用紙パッケージの膨潤程度よりも 小さい場合には、 用紙の両側端縁と用紙パッケージにおける箱状体の側壁内面と の間に必要以上に隙間が発生してしまう。 この場合には、 プリンタ等の紙送り機 構による紙送り時に用紙が重なった状態で送り出される重送現象を発生してしま う問題がある。  For example, when the degree of swelling of the paper is greater than the degree of swelling of the paper package, both side edges of the paper strongly contact the inner surface of the side wall of the box-shaped body in the paper package. In this case, the frictional force between the two becomes unnecessarily large, and as a result, there is a problem that the paper is not fed out at the time of paper feeding by a paper feeding mechanism such as a printer, and the idle feeding occurs. If the degree of swelling of the paper is smaller than the degree of swelling of the paper package, a gap is generated more than necessary between the side edges of the paper and the inner surface of the side wall of the box in the paper package. In this case, there is a problem that a double feed phenomenon occurs in which the paper is fed out in an overlapping state when the paper is fed by a paper feed mechanism such as a printer.
本発明は前記従来における問題点を解消するためになされたものであり、 紙材 から構成されているにもかかわらず、 湿度の影響が比較的小さく、 用紙を一枚ず つ安定的に送り出すことが可能な用紙パッケージを提供することを目的とする。 前記目的を達成するため、 本発明に係る用紙パッケージは、 用紙を積層した状 態で収納する箱状体を有し、 紙材から形成された用紙パッケージであって、 前記 用紙を構成する紙繊維の方向と前記用紙パッケージの箱状体を構成する紙繊維の 方向とを略同一方向にしたことを特徴とする。  SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and has a relatively small influence of humidity and is capable of stably feeding out sheets one by one despite being made of paper. It is an object of the present invention to provide a paper package capable of performing the following. In order to achieve the above object, a paper package according to the present invention has a box-shaped body for storing paper in a stacked state, and is a paper package formed from paper material, wherein the paper fiber constituting the paper is provided. And the directions of the paper fibers forming the box-shaped body of the paper package are substantially the same.
このように構成された用紙パッケージでは、 用紙と用紙パッケージの双方につ き湿度の影響を受け難くするとともに、 膨潤の程度を小さく し、 両者の膨潤特性 を同等にすることが可能となる。 これにより、 用紙の両側端縁と箱状体の側壁内 面との間における摩擦力を略一定にして、 箱状体から用紙を一枚ずつ安定的に送 り出すことができる。 図面の簡単な説明 In a paper package configured in this way, both the paper and the paper package In addition to being less susceptible to the effects of humidity, the degree of swelling can be reduced and the swelling characteristics of both can be made equal. Thereby, the frictional force between the side edges of the paper and the inner surface of the side wall of the box is made substantially constant, and the paper can be stably sent out one by one from the box.

FIG. 1 is a perspective view of a paper package, and FIG. 2 is a perspective view schematically showing a state in which paper is set in the paper package.
第 1図及び第 2図において、 用紙パッケージ 9は、 例えば、 A 6〜A 7サイズ 程度の小さいサイズを有するカツ トシ一ト状の感熱紙 7を複数枚積層した状態で、 紙材から形成された箱状体 8の内部に収納してなる。かかる用紙パッケージ 9は、 第 1図に示すように、 箱状体 8から感熱紙 7の一部を露出させた状態で、 箱状体 8と共に後述するプリン夕 1にセッ トできるように構成されている。  1 and 2, the paper package 9 is formed from a paper material in a state where a plurality of cut-sheet-shaped thermal papers 7 having a small size of, for example, A6 to A7 are stacked. It is housed inside the box-shaped body 8. As shown in FIG. 1, the paper package 9 is configured such that a part of the thermal paper 7 is exposed from the box-shaped body 8 and can be set together with the box-shaped body 8 in a pudding unit 1 described later. ing.
前記箱状体 8は、 第 2図に示すように、 感熱紙 7が挿入される側が開放された 箱形の本体 8 dと、 本体 8 dの開放側の下面から延在するように設けられた蓋部 8 cとを備えている。 感熱紙 7は、 その印字面を下側へ向けつつ複数枚積層され た状態で、 本体 8 dの開放側から第 2図における矢印 A方向に挿入される。 蓋部 8 cは、 用紙パッケージ 9を使用しないときには感熱紙 7を覆って閉じた 状態になっているが、 プリン夕 1にセッ 卜するときには蓋部 8 cを開いて下方へ 折り返すことにより、 第 1図に示すように感熱紙 7の一部を露出させることが可 能になっている。 As shown in FIG. 2, the box-shaped body 8 is provided so as to extend from a box-shaped main body 8 d having an open side on which the thermal paper 7 is inserted, and a lower surface on the open side of the main body 8 d. Lid portion 8c. The thermal paper 7 is inserted in the direction of arrow A in FIG. 2 from the open side of the main body 8d in a state where a plurality of thermal papers 7 are stacked with their print surfaces facing downward. When the paper package 9 is not used, the lid 8 c is closed by covering the thermal paper 7 .When the lid 8 c is set on the pudding 1, the lid 8 c is opened and folded down. As shown in FIG. 1, a part of the thermal paper 7 can be exposed.
本体 8 dの上壁部 8 h (第 6図参照） から一体に延出され、 感熱紙 7の上面に 位置するべ口部 8 eは、 露出させた状態の感熱紙 7を支持するとともに、 第 1図 の用紙パッケージ 9をプリン夕 1 にセッ トしたときに、 後述する押圧板 1 8と感 熱紙 7 との間に介在されるようになっており、 感熱紙 7 との間に適宜の摩擦力を 発生させて、 感熱紙 7を一枚毎にスムーズに分離できるように構成されている。 尚、箱形に形成された本体 8 dの両側には側壁部 8 gがー体に設けられており、 本体 8 d内に感熱紙 7を積層した状態で収納した際には、 感熱紙 7の両側端縁と 各側壁部 8 gの内面とは、 略一定の摩擦力をもって相互に接触している。  The opening 8e, which extends integrally from the upper wall 8h (see Fig. 6) of the main body 8d and is located on the upper surface of the thermal paper 7, supports the thermal paper 7 in an exposed state, When the paper package 9 shown in Fig. 1 is set in the printer 1, it is interposed between the press plate 18 and the thermal paper 7, which will be described later. The frictional force is generated so that the thermal paper 7 can be separated smoothly one by one. In addition, a side wall 8 g is provided on both sides of the main body 8 d formed in a box shape, and when the thermal paper 7 is stored in a stacked state in the main body 8 d, the thermal paper 7 And the inner surfaces of the side walls 8 g are in contact with each other with a substantially constant frictional force.
本体 8 dの前記開放側と反対側の一隅は、 斜め 4 5 ° にカッ トされて切欠 8 a が形成され、 かつ、 当該切欠 8 aの位置には、 斜状壁 8 f が設けられている。 一 方、 感熱紙 7には、 正しい向きで箱状体 8の本体 8 d内に挿入されたときに斜状 壁 8 f に対応する位置に、 同様の切欠 7 aが形成されている。  One corner of the main body 8d opposite to the open side is cut at an angle of 45 ° to form a notch 8a, and a beveled wall 8f is provided at the position of the notch 8a. I have. On the other hand, a similar cutout 7a is formed in the thermal paper 7 at a position corresponding to the oblique wall 8f when inserted into the main body 8d of the box-shaped body 8 in a correct orientation.
従って、 感熱紙 7を第 2図に示す正しい向きにした状態で本体 8 dに揷入した ときは、 斜状壁 8は感熱紙 7の切欠 7 aに位置することとなる。 これと同時に、 切欠 7 aは本体 8 dの切欠 8 aと重なり、 この結果、 用紙パッケージ 9全体とし ての切欠 9 a (第 1図参照） が形成されるようになっている。  Accordingly, when the thermal paper 7 is inserted into the main body 8d with the correct orientation shown in FIG. 2, the inclined wall 8 is located in the notch 7a of the thermal paper 7. At the same time, the notch 7a overlaps with the notch 8a of the main body 8d, and as a result, the notch 9a (see FIG. 1) of the entire paper package 9 is formed.
一方、 第 2図に示される向き以外の向きで感熱紙 7を箱状体 8の本体 8 d内へ 挿入した際には、 感熱紙 7の切欠 7 aが形成されていない隅部が斜状壁 8 f と干 渉するので、 感熱紙 7を箱状体 8の奥までセッ トできず、 この結果、 用紙パッケ ージ 9全体も、プリン夕 1の後述する用紙収納部 6にセッ 卜できないこととなる。 この構成により、 感熱紙 7の向きが正しくプリンタ 1にセッ トさせることが保証 される。  On the other hand, when the thermal paper 7 is inserted into the main body 8 d of the box-shaped body 8 in a direction other than that shown in FIG. 2, the corners of the thermal paper 7 where the notches 7 a are not formed are inclined. Because of the interference with the wall 8 f, the thermal paper 7 cannot be set all the way to the back of the box 8, and as a result, the entire paper package 9 cannot be set in the paper storage section 6 of the printer 1, which will be described later. It will be. This configuration guarantees that the thermal paper 7 is correctly set in the printer 1.
感熱紙 7は、 感熱することにより印字される印字面がその一面側に形成されて おり、 前述のように、 当該印字面が下にされた状態で重ねられて、 箱状体 8と共 にプリン夕 1にセッ 卜される。 感熱紙 7としては、 加熱により発色する発色層を有する感熱発色タイプのもの や、 加熱により穿孔される穿孔層を基材層に積層した感熱穿孔タイプのもの等、 種々のものを使用することができる。 また、 感熱ラベルのようなものであっても よい。 The thermal paper 7 has a printing surface to be printed by heat on one side thereof. As described above, the thermal paper 7 is stacked with the printing surface down, and together with the box-shaped body 8. Set in pudding evening 1. As the thermal paper 7, there can be used various types such as a thermal coloring type having a coloring layer which develops color by heating, and a thermal punching type wherein a perforated layer formed by heating is laminated on a base material layer. it can. Also, it may be something like a thermal label.
ここで、 感熱紙 7を構成する紙繊維の配列方向と紙材からなる箱状体 8を構成 する紙繊維の配列方向との関係について、 第 2図に基づき説明する。 感熱紙 7に は、 その紙繊維が一方向に配列された紙材が使用されており、 紙繊維の配列方向 は、第 2図における矢印 B方向（長方形状を有する感熱紙 7の長手方向）である。 また、 箱状体 8の本体 8 dを構成する、 少なくとも、 上壁部 8 h、 蓋部 8 c 、 ベロ部 8 eには、 その紙繊維が一方向に配列された紙材が使用されており、 紙繊 維の配列方向は、 第 2図における矢印 C (長方形状を有する本体 8 dの長手方向） である。  Here, the relationship between the arrangement direction of the paper fibers constituting the thermal paper 7 and the arrangement direction of the paper fibers constituting the box-shaped body 8 made of paper will be described with reference to FIG. As the thermal paper 7, a paper material in which paper fibers are arranged in one direction is used, and the paper fibers are arranged in the direction of arrow B in FIG. 2 (the longitudinal direction of the thermal paper 7 having a rectangular shape). It is. Further, at least the upper wall portion 8h, the lid portion 8c, and the tongue portion 8e constituting the main body 8d of the box-shaped body 8 are made of a paper material in which the paper fibers are arranged in one direction. The arrangement direction of the paper fibers is indicated by an arrow C in FIG. 2 (the longitudinal direction of the main body 8d having a rectangular shape).
そして、 箱状体 8の本体 8 d内にその開放側から感熱紙 7を挿入して収納され た状態においては、 感熱紙 7における紙繊維の配列方向 （矢印 B方向） と本体 8 dにを構成する上壁部 8 h、蓋部 8 c、ベロ部 8 eにおける紙繊維の配列方向（矢 印 C方向） は、 略同一の方向となる。  When the thermal paper 7 is inserted and stored in the main body 8 d of the box-shaped body 8 from its open side, the arrangement direction of the paper fibers in the thermal paper 7 (the direction of arrow B) and the main body 8 d are aligned. The arrangement direction (the direction of arrow C) of the paper fibers in the upper wall portion 8h, the lid portion 8c, and the tongue portion 8e that are configured is substantially the same direction.
前述のように、 本実施形態に係る用紙パッケージ 9では、 箱状体 8が紙材から 形成されている。感熱紙 7と箱状体 8の本体 8 dにおける上壁部 8 h、蓋部 8 c 、 ベロ部 8 e との紙繊維の配列方向に対しては湿度の影響を受け難く膨潤の程度を 小さく して膨潤特性を同等にできることを勘案し、 感熱紙 7における紙繊維の配 列方向 （矢印 B方向） と上壁部 8 h、 蓋部 8 c、 ベロ部 8 eの紙繊維の配列方向 (矢印 C方向） とを略同一方向にしているので、 感熱紙 7と本体 8 dの双方につ き湿度の影響を受け難くして膨潤の程度を小さく し、 両者の膨潤特性を同等にす ることが可能となる。 これにより、 感熱紙 7の両側端縁と本体 8 dの側壁部 8 g の内面との間における摩擦力を略一定にして、 用紙パッケージ 9から感熱紙 7を 一枚ずつ安定的に送り出すことができる。  As described above, in the paper package 9 according to the present embodiment, the box-shaped body 8 is formed from a paper material. The degree of swelling is small because it is hardly affected by the humidity in the paper fiber arrangement direction of the upper wall 8h, the lid 8c, and the tongue 8e of the thermal paper 7 and the main body 8d of the box-shaped body 8d. Taking into account that the swelling characteristics can be made equal to each other, the arrangement direction of the paper fibers (in the direction of arrow B) of the thermal paper 7 and the arrangement direction of the paper fibers of the upper wall 8h, the lid 8c, and the velvet 8e ( (In the direction of arrow C) are substantially in the same direction, so that both the thermal paper 7 and the main body 8d are hardly affected by humidity, the degree of swelling is reduced, and the swelling characteristics of both are made equal. It becomes possible. As a result, the frictional force between both side edges of the thermal paper 7 and the inner surface of the side wall 8 g of the main body 8 d is made substantially constant, and the thermal paper 7 can be stably sent out one by one from the paper package 9. it can.
また、 本体 8 d内に挿入され積層状態で収納された感熱紙 7において、 感熱紙 7と感熱紙 7との間に発生する摩擦力は、 感熱紙 7と本体 8 dのべ口部 8 e、 上 壁部 8 hの内面 （下面） との間に発生する摩擦力よりも小さく設定されている。 このように構成することにより、 積層状態の感熱紙 7を本体 8 dから一枚ずつ順 次送り出すことが可能となり、 更に、 感熱紙 7の積層数が少なくなつた場合にお いても、 最後の一枚まで適正に送り出すことが可能となる。 In the thermal paper 7 inserted into the main body 8d and stored in a stacked state, the frictional force generated between the thermal paper 7 and the thermal paper 7 is the thickness 8e of the thermal paper 7 and the main body 8d. It is set to be smaller than the frictional force generated between the upper wall 8h and the inner surface (lower surface). With this configuration, it is possible to sequentially feed out the stacked thermal papers 7 one by one from the main body 8d.Furthermore, even when the number of the thermal papers 7 is reduced, It is possible to properly feed up to one sheet.
尚、 感熱紙 7における紙繊維の配列方向 （矢印 B方向） は、 後述するプリンタ 1におけるピックアップローラ 1 2等を介して送り出される用紙搬送方向と略同 一方向にされている。  Note that the arrangement direction of the paper fibers in the thermal paper 7 (the direction of arrow B) is substantially the same as the paper conveyance direction sent out via the pickup rollers 12 and the like in the printer 1 described later.
続いて、 前記した用紙パッケージ 9が使用されるプリン夕 1の概略構成につい て、 第 3図乃至第 7図に基づき説明する。 第 3図はプリン夕の斜視図、 第 4図は プリン夕の側断面図、第 5図は用紙収容部に用紙をセッ 卜した状態を示す斜視図、 第 6図は用紙収容部に用紙をセッ トした状態を示す側断面図、 第 7図は用紙分離 部及び印刷機構の詳細を示す拡大断面図である。  Next, a schematic configuration of the printer 1 in which the above-described paper package 9 is used will be described with reference to FIGS. 3 to 7. FIG. Fig. 3 is a perspective view of the pudding, Fig. 4 is a side sectional view of the pudding, Fig. 5 is a perspective view showing a state in which paper is set in the paper storage unit, and Fig. 6 is a paper in the paper storage unit. FIG. 7 is a side sectional view showing a set state, and FIG. 7 is an enlarged sectional view showing details of a sheet separating section and a printing mechanism.
プリ ンタ 1は、 第 3図に示すように、 平面視で長方形状 （A 6〜A 7サイズ程 度の大きさ） とされ、 かつ、 厚さが略 2 c mあるいはそれ以下とされた、 コンパ ク トな構成とされている。 プリンタ 1の本体ケース 2は、 枠体 3の下面を下カバ 一 4で覆うとともに、 上面の一部を上カバー 5で覆って形成されている。  As shown in FIG. 3, the printer 1 has a rectangular shape (a size of about A6 to A7) in plan view and a thickness of about 2 cm or less. It has a simple configuration. The main body case 2 of the printer 1 is formed by covering the lower surface of the frame 3 with the lower cover 4 and partially covering the upper surface with the upper cover 5.
枠体 3の上面側のうち前記上カバ一 5で覆われた箇所を除いた残りの部分には、 第 4図に示すように用紙収容部 （給紙部） 6が形成されている。 この用紙収容部 6には、上述した用紙パッケージ 9を、第 6図に示すように収容可能としている。 前記用紙収容部 6の上方は蓋体 1 0にて覆われ、 この蓋体 1 0は第 4図に示す ように回動することにより開閉自在とされている。 本体ケース 2側には図示しな いロック機構が設けられており、 前述のように用紙収容部 6に用紙パッケージ 9 をセッ 卜した状態で、 第 6図に示すように蓋体 1 0を閉じてロックできるように なっている。  In the remaining portion of the upper surface of the frame 3 except for the portion covered with the upper cover 5, a paper storage portion (paper feed portion) 6 is formed as shown in FIG. In the paper storage section 6, the above-described paper package 9 can be stored as shown in FIG. The upper part of the paper storage unit 6 is covered with a lid 10 which can be opened and closed by rotating as shown in FIG. A lock mechanism (not shown) is provided on the main body case 2 side.When the paper package 9 is set in the paper storage section 6 as described above, the lid 10 is closed as shown in FIG. Can be locked.
用紙収容部 6の一側の端部には、 用紙分離部 1 1 としてのピックアップローラ 1 2及び分離ブロック 1 3等が配置されている。 また、 上カバー 5の下方には、 後述する印刷機構部 1 4としてのサーマルヘッ ド 1 5、 プラテンローラ 1 6、 ぺ —パーガイ ド 1 7が配置される。  At one end of the sheet storage unit 6, a pickup roller 12 and a separation block 13 as a sheet separation unit 11 are arranged. Further, below the upper cover 5, a thermal head 15 as a printing mechanism unit 14, a platen roller 16 and a paper guide 17, which will be described later, are arranged.
また、 用紙収容部 6の他端側の一隅には、 第 5図に示すように用紙収容部 6内 に突出した斜状の凸部 （規制部） 6 aが設けられている。 この凸部 6 aは、 上述 した用紙パッケージ 9の切欠 9 aと合致する形状とされている。 In addition, at one corner of the other end side of the paper storage unit 6, an inclined convex portion (restriction portion) 6 a protruding into the paper storage unit 6 is provided as shown in FIG. This projection 6a is It has a shape that matches the notch 9 a of the paper package 9.
従って、 この凸部 6 aは、 用紙パッケージ 9が用紙収容部 6内に正しい方向で セッ トされると切欠 9 aの部分に位置するが、 そうでない場合には、 用紙パッケ ージ 9の切欠 9 aを形成した以外の隅部と凸部 6 aが干渉するようになっている c これにより、 プリン夕 1に対する用紙パッケージ 9の誤った向きでのセッ トを 防止できるようになっている。 Therefore, the convex portion 6a is located at the notch 9a when the paper package 9 is set in the paper receiving portion 6 in the correct direction, but otherwise, the notch of the paper package 9 is provided. The corners other than the corners where 9a are formed and the projections 6a interfere with each other. C. This prevents the paper package 9 from being set in the wrong direction with respect to the printer 1.
次に、 用紙分離部 1 1について説明する。  Next, the paper separating unit 11 will be described.
前記用紙収容部 6において、 印刷機構部 1 4に近い側の端部には、 ピックアツ プローラ 1 2と分離ブロック 1 3とが設けられている。 前記蓋体 1 0の用紙収容 部 6側を向く内面には、 押圧板 1 8が回動自在に支持されている。 この押圧板 1 8と蓋体 1 0との間にはコイル状の付勢パネ 1 9が介在され、 押圧板 1 8に対し て押圧板 1 8を下方へ回動させる向きの付勢力を常時作用させている。  In the paper storage section 6, a pick-up roller 12 and a separation block 13 are provided at an end near the printing mechanism section 14. A pressing plate 18 is rotatably supported on the inner surface of the lid 10 facing the paper storage unit 6 side. A coil-shaped biasing panel 19 is interposed between the pressing plate 18 and the lid 10, and constantly provides a biasing force in a direction for rotating the pressing plate 18 downward with respect to the pressing plate 18. Is working.
上述した用紙パッケージ 9は、 第 6図に示すように、 印字面を下側に向けなが ら積層された状態で内部に収納されている感熱紙 7のうち、 最も下側に位置する 感熱紙 7の下面を箱状体 8から一部露出させた状態で、 用紙収容部 6にセッ トさ れる。 そして、 前記蓋体 1 0を閉じてロックした際には、 前述の付勢パネ 1 9に より下方へ付勢される押圧板 1 8が、 箱状体 8のべ口部 8 eを介して、 感熱紙 7 の前記露出した部分をピックアップローラ 1 2側へ押し付け、 感熱紙 7の下面を ピックアップローラ 1 2に接触させる。  As shown in FIG. 6, the paper package 9 described above is the lowest thermal paper among the thermal papers 7 stored inside with the printed surface facing down. 7 is set in the paper storage unit 6 with the lower surface of the 7 partially exposed from the box-shaped body 8. Then, when the lid 10 is closed and locked, the pressing plate 18 urged downward by the urging panel 19 described above moves through the mouth 8 e of the box-shaped body 8. Then, the exposed portion of the thermal paper 7 is pressed against the pickup roller 12 side, and the lower surface of the thermal paper 7 is brought into contact with the pickup roller 12.
前記ピックアップローラ 1 2に近接させて分離ブロック 1 3が設けられ、 この 分離ブロック 1 3は、 ピックアップローラ 1 7の用紙送り出し方向に対して傾斜 した分離案内面 1 3 aを備えている。  A separation block 13 is provided close to the pickup roller 12, and the separation block 13 has a separation guide surface 13 a inclined with respect to the sheet feeding direction of the pickup roller 17.
この構成でピックアップローラ 1 2が回転駆動することにより、 ピックアップ ローラ 1 2に接触する最下層の感熱紙 7に搬送力が加えられる。 そして、 前記分 離ブロック 1 3の分離案内面 1 3 aの分離作用と相まって、 最下層に位置する一 枚の感熱紙 7のみが分離されて印刷機構部 1 4に送り出される。 すなわち、 最下 層の感熱紙 7は付勢バネ 1 9が用紙 7をピックアップローラ 1 2に向けて付勢す ることにより発生するピックアップローラ 1 2の搬送力が、 分離案内面 1 3 aか ら受けるブレーキ力、 さらにその上の感熱紙 7から受ける負の摩擦力を上回るこ とで搬送される。 搬送される感熱紙 7の上の （下から 2枚目の） 感熱紙 7には、 最下層の感熱紙 7から受ける正の摩擦力、 その上の （下から 3枚目の） 用紙から 受ける負の摩擦力と分離案内面 1 3 aから受けるブレーキ力が働き、 その位置に 留まる。 従って、 最下層の感熱紙 7のみが搬送されることになり、 重送は起きな い。 By rotating the pickup roller 12 in this configuration, a conveying force is applied to the lowermost thermal paper 7 that contacts the pickup roller 12. Then, in combination with the separation action of the separation guide surface 13 a of the separation block 13, only one sheet of thermal paper 7 located at the lowermost layer is separated and sent to the printing mechanism unit 14. That is, the transfer force of the pickup roller 12 generated when the urging spring 19 urges the paper 7 toward the pickup roller 12 causes the transfer force of the separation guide surface 13 a of the lowermost layer of the thermal paper 7 to be increased. Braking force received from the thermal paper 7 And transported. The thermal paper 7 on the thermal paper 7 being conveyed (the second from the bottom) has a positive frictional force from the lowermost thermal paper 7, and the thermal paper 7 on the third paper from the bottom The negative frictional force and the braking force received from the separation guide surface 13a work to stay at that position. Therefore, only the lowermost thermal paper 7 is transported, and no double feed occurs.
このとき、 ピックアップローラ 1 2よる感熱紙 7の送り出し方向は、 第 6図に 示すように、 用紙パッケージ 9の長手方向であり、 かかる送り出し方向は、 用紙 パッケージ 9における箱状体 8の本体 8 d内に収納されている感熱紙 7の紙繊維 の配列方向 （矢印 B及び矢印 C方向） と略同一となる。 従って、 ピックアップ口 —ラ 1 2より感熱紙 7が受ける張力方向と感熱紙 7における紙繊維の配列方向と が略同一となることから、 感熱紙 7においてカールが発生することを防止するこ とができる。  At this time, the feeding direction of the thermal paper 7 by the pickup roller 1 2 is the longitudinal direction of the paper package 9 as shown in FIG. 6, and the feeding direction is the main body 8 d of the box 8 in the paper package 9. It is almost the same as the arrangement direction of the paper fibers of the thermal paper 7 stored in the inside (the directions of arrows B and C). Accordingly, since the direction of the tension applied to the thermal paper 7 from the pickup opening 1 and the arrangement direction of the paper fibers in the thermal paper 7 are substantially the same, it is possible to prevent the thermal paper 7 from being curled. it can.
次に、 印刷機構部 1 4について説明する。  Next, the printing mechanism 14 will be described.
分離ブロック 1 3に隣接してプラテンローラ 1 6が回転自在に設けられ、 その 外周面に近接させてペーパーガイ ド 1 7が配置される。 第 7図の拡大図に示すよ うに、 このペーパーガイ ド 1 7には、 前記プラテンローラ 6 1の外周面に沿うよ うに、 断面が横向き略 「U」 字状となるような凹湾曲状の周接面 1 7 aが形成さ れている。 ペーパーガイ ド 1 7と本体ケース 2との間には押圧コイルバネ 2 0が 設けられており、 前記周接面 1 7 aをプラテンローラ 1 6の外周面に向けて付勢 するようになつている。  A platen roller 16 is rotatably provided adjacent to the separation block 13, and a paper guide 17 is arranged near the outer peripheral surface thereof. As shown in the enlarged view of FIG. 7, this paper guide 17 has a concave curved shape such that the cross section is substantially U-shaped in a horizontal direction along the outer peripheral surface of the platen roller 61. A circumferential contact surface 17a is formed. A pressing coil spring 20 is provided between the paper guide 17 and the main body case 2 so as to urge the peripheral contact surface 17 a toward the outer peripheral surface of the platen roller 16. .
この構成において、 前述の用紙分離部 1 1で分離された感熱紙 7は、 ピックァ ップローラ 1 2により搬送されて、 分離ブロック 1 3の下端と、 感熱紙 7の向き をプラテンローラ 1 6側へ向けるためのガイ ド板 2 1の間を通過する。  In this configuration, the thermal paper 7 separated by the paper separating unit 11 described above is conveyed by the pick-up roller 12 and the lower end of the separation block 13 and the direction of the thermal paper 7 are directed to the platen roller 16 side. Pass between the guide plates 21.
感熱紙 7はガイ ド板 2 1により案内され、 プラテンローラ 1 6の下面側から、 プラテンローラ 1 6とペーパーガイ ド 1 7 との間に送られる。そして感熱紙 7は、 プラテンローラ 1 6の外周面とペーパーガイ ド 1 7の周接面 1 7 aとの間で保持 されつつ、 プラテンローラ 1 6の回転駆動により横向き 「U」 字状に反転されな がら搬送され、 印字面を上側に向けながらプラテンローラ 1 6の上面側に至る。  The thermal paper 7 is guided by the guide plate 21 and is sent from the lower surface of the platen roller 16 to between the platen roller 16 and the paper guide 17. The thermal paper 7 is held between the outer peripheral surface of the platen roller 16 and the peripheral contact surface 17 a of the paper guide 17, and is rotated in a horizontal “U” shape by rotating the platen roller 16. The paper is conveyed while reaching the upper surface of the platen roller 16 with the printing surface facing upward.
ローラ 1 6の上面側に位置するサーマルへッ ド 1 5は、 印字部たる発 熱体部 1 5 aを有している。 このサーマルへッ ド 1 5は回動軸 1 5 bの回りに回 動可能に設けられて、 発熱体部 1 5 aがプラテンローラ 1 6の上面に接離可能と されている。 The thermal head 15 located on the top side of the roller 16 It has a heating element 15a. The thermal head 15 is provided so as to be rotatable around a rotating shaft 15 b, and the heating element 15 a can be brought into contact with and separated from the upper surface of the platen roller 16.
尚、 このようにサーマルヘッ ド 1 5を回動自在に構成したのは、 プラテンロー ラ 1 6とペーパーガイ ド 1 7との間で感熱紙 7が詰まった場合におけるジャム紙 除去作業において、 サ一マルへッ ド 1 5が作業の邪魔にならないようにするため である。  The reason why the thermal head 15 is configured to be rotatable in this manner is that when the thermal paper 7 is jammed between the platen roller 16 and the paper guide 17, the jam paper removal operation is performed in the same manner. This is to prevent the head 15 from interfering with the work.
サーマルヘッ ド 1 5には戻りコイルバネタイプのスプリング 2 2の一端が係止 されて、 サーマルへッ ド 1 5の発熱体部 1 5 aがプラテンローラ 1 6上面に近接 する方向の付勢力を常時加えている。  One end of a return coil spring type spring 22 is locked to the thermal head 15, so that the heating element 15 a of the thermal head 15 always applies a biasing force in the direction approaching the upper surface of the platen roller 16. ing.
この構成で、 前述のように印字面を上側向けながらプラテンローラ 1 6により 送られてくる感熱紙 7の上面にサ一マルへッ ド 1 5の発熱体部 1 5 aが接触し、 この接触する箇所において感熱紙 7に印字がなされる。  With this configuration, the heating element 15a of the thermal head 15 comes into contact with the upper surface of the thermal paper 7 sent by the platen roller 16 while the print surface faces upward, as described above. The printing is performed on the thermal paper 7 at the place where the printing is performed.
サ一マルヘッ ド 1 5はラインヘッ ド型とされ、 搬送されてくる感熱紙 7に対し て、 感熱紙 7の搬送方向に直交する方向に延びるライン毎に、 任意の文字や画像 を印刷することができる。 一本のラインにつき印刷する際の印刷幅は、 印刷対象 の感熱紙 7の幅に略等しく設定されている。  The thermal head 15 is a line head type, and it is possible to print arbitrary characters and images on the thermal paper 7 to be transported for each line extending in the direction perpendicular to the transport direction of the thermal paper 7. it can. The printing width when printing per line is set substantially equal to the width of the thermal paper 7 to be printed.
このようにサーマルへッ ド 1 5を印刷へッ ドとして用いるのは、 感熱紙 7を用 いることにより、 インクやインクリボン等の消耗品を不要とできる他、 インク供 給のための機構等を省略でき、プリン夕 1をコンパク 卜に構成できるからである。 前記分離ブロック 1 3には、 プラテンローラ 1 6の用紙送り出し方向に対して 傾斜した排紙ガイ ド面 1 3 bが形成されている。  The reason why the thermal head 15 is used as the printing head is that the use of the thermal paper 7 eliminates the need for consumables such as ink and ink ribbon, and also provides a mechanism for supplying ink. Can be omitted, and pudding 1 can be made compact. The separation block 13 has a paper discharge guide surface 13 b that is inclined with respect to the paper feed direction of the platen roller 16.
この構成において、 サーマルへッ ド 1 5の発熱体部 1 5 aにより印字がなされ た後の感熱紙 7は、 この排紙ガイ ド面 1 3 bにより案内されて、 第 3図に示すよ うに、 本体ケース 2の上カバー 5と蓋体 1 0とがなす隙間から、 蓋体 1 0の上側 に排紙される。  In this configuration, the thermal paper 7 after printing by the heating element 15a of the thermal head 15 is guided by the paper ejection guide surface 13b, as shown in FIG. The paper is discharged to the upper side of the lid 10 through a gap formed between the upper cover 5 of the main body case 2 and the lid 10.
以上説明したように、 プリンタ 1は、 用紙収容部 6にセッ トした感熱紙 7の下 面側がサーマルへッ ド 1 5に対向するように送られ、 サーマルへッ ド 1 5にて印 字を行うようになっている。 このことから、 用紙収容部 6には、 感熱紙 7の印字 面 （感熱面） が下面に配置されるように、 表裏を間違えずにセッ トすることが要 求される。 As described above, the printer 1 is fed so that the lower side of the thermal paper 7 set in the paper storage unit 6 faces the thermal head 15, and prints on the thermal head 15. It is supposed to do. For this reason, the thermal storage paper 7 is printed on the paper It is required that the front and back sides be set correctly so that the surface (thermosensitive surface) is placed on the lower surface.
この点、 本実施形態に係る用紙パッケージ 9は、 その箱状体 8に感熱紙 7を正 しい向きでセッ トするときには、 その感熱紙 7に設けられている切欠 7 aの部分 に位置して感熱紙 7のセッ トを可能とし、 かつ、 感熱紙 7をそれ以外の向きで箱 状体 8にセッ トする際にはその感熱紙 7 と干渉して感熱紙 7のセッ トを不可能と する斜状壁 8 f が設けられている。  In this regard, when the thermal paper 7 is set in the correct orientation in the box-shaped body 8, the paper package 9 according to the present embodiment is located at the cutout 7 a provided in the thermal paper 7. The thermal paper 7 can be set, and when the thermal paper 7 is set on the box-shaped body 8 in any other direction, it interferes with the thermal paper 7 and the thermal paper 7 cannot be set. An inclined wall 8 f is provided.
従って、 感熱紙 7をプリンタ 1にセッ トする際に誤った向きでセッ 卜すること が斜状壁 8 f を介して防止されるため、 感熱紙 7を表裏及び前後向き共に正しく 挿入してセッ トすることができ、 印刷トラブルを防止することができる。  Therefore, it is possible to prevent the thermal paper 7 from being set in the wrong direction when the thermal paper 7 is set in the printer 1 through the inclined wall 8f. Printing troubles can be prevented.
以上詳細に説明した通り本実施形態に係る用紙パッケージ 9では、 箱状体 8を 紙材から形成するとともに、感熱紙 7と箱状体 8の本体 8 dにおける上壁部 8 h、 蓋部 8 c、 ベロ部 8 eとの紙繊維の配列方向に対しては湿度の影響を受け難く膨 潤の程度を小さく して膨潤特性を同等にできることを勘案し、 感熱紙 7における 紙繊維の配列方向 （矢印 B方向） と上壁部 8 h、 蓋部 8 c、 ベロ部 8 eの紙繊維 の配列方向 （矢印 C方向） とを略同一方向にしているので、 感熱紙 7と本体 8 d の双方につき湿度の影響を受け難く して膨潤の程度を小さく し、 両者の膨潤特性 を同等にすることが可能となる。 これにより、 感熱紙 7の両側端縁と本体 8 dの 側壁部 8 gの内面との間における摩擦力を略一定にして、 用紙パッケージ 9から 感熱紙 7を一枚ずつ安定的に送り出すことができる。  As described in detail above, in the paper package 9 according to the present embodiment, the box-shaped body 8 is formed from a paper material, and the heat-sensitive paper 7 and the upper wall 8 h and the lid 8 of the main body 8 d of the box-shaped body 8 are formed. c, the arrangement direction of the paper fibers in the thermal paper 7 taking into account that the arrangement direction of the paper fibers with the tongue section 8 e is less affected by humidity and the degree of swelling can be reduced and the swelling characteristics can be made equal. (Direction of arrow B) and the arrangement direction of the paper fibers (direction of arrow C) of the upper wall portion 8h, the lid portion 8c, and the tongue portion 8e are substantially in the same direction. It is possible to reduce the degree of swelling by making the two less susceptible to the influence of humidity, and to make the swelling characteristics of both equal. As a result, the frictional force between the side edges of the thermal paper 7 and the inner surface of the side wall 8 g of the main body 8 d is made substantially constant, and the thermal paper 7 can be stably sent out one by one from the paper package 9. it can.
また、 本体 8 d内に挿入され積層状態で収納された感熱紙 7において、 感熱紙 7と感熱紙 7との間に発生する摩擦力は、 感熱紙 7 と本体 8 dのべ口部 8 e、 上 壁部 8 hの内面 （下面） との間に発生する摩擦力よりも小さく設定されている。 このように構成することにより、 積層状態の感熱紙 7を本体 8 dから一枚ずつ順 次送り出すことが可能となり、 更に、 感熱紙 7の積層数が少なくなつた場合にお いても、 最後の一枚まで適正に送り出すことが可能となる。  In the thermal paper 7 inserted in the main body 8 d and stored in a stacked state, the frictional force generated between the thermal paper 7 and the thermal paper 7 is the thickness 8 e of the thermal paper 7 and the main body 8 d. It is set to be smaller than the frictional force generated between the upper wall 8h and the inner surface (lower surface). With this configuration, it is possible to sequentially feed out the stacked thermal papers 7 one by one from the main body 8d.Furthermore, even when the number of the thermal papers 7 is reduced, It is possible to properly feed up to one sheet.
更に、 ピックアップローラ 1 2よる感熱紙 7の送り出し方向は、 第 6図に示す ように、 用紙パッケージ 9の長手方向であり、 かかる送り出し方向は、 用紙パッ ケージ 9における箱状体 8の本体 8 d内に収納されている感熱紙 7の紙繊維の配 列方向 （矢印 B及び矢印 C方向） と略同一となり、 従って、 ピックアップローラ 1 2より感熱紙 7が受ける張力方向と感熱紙 7における紙繊維の配列方向とが略 同一となることから、 感熱紙 7においてカールが発生することを防止することが できる。 Further, as shown in FIG. 6, the feeding direction of the thermal paper 7 by the pickup roller 12 is the longitudinal direction of the paper package 9, and the feeding direction is the main body 8 d of the box 8 in the paper package 9. Arrangement of paper fibers of thermal paper 7 stored inside Since the direction of the tension applied to the thermal paper 7 from the pickup roller 12 and the arrangement direction of the paper fibers in the thermal paper 7 are substantially the same as the row direction (the directions of the arrows B and C), the thermal paper 7, curling can be prevented.
尚、 本発明は前記実施形態に限定されるもではなく、 本発明の要旨を逸脱しな い範囲内で種々の改良、 変形が可能であることは勿論である。  It should be noted that the present invention is not limited to the above-described embodiment, and various improvements and modifications can be made without departing from the spirit of the present invention.
上記実施形態においては、 感熱紙 7を用いたプリン夕を例として説明したが、 本発明の用紙パッケージは、 プリン夕用の感熱紙 7のパッケージに限定されるも のではなく、 感熱紙以外の力ッ ト紙を用いる様々な機器の用紙パッケージとして 用いることが可能である。 産業上の利用可能性  In the above embodiment, the printing paper using the thermal paper 7 has been described as an example, but the paper package of the present invention is not limited to the thermal paper 7 package for the printing paper. It can be used as a paper package for various devices that use proof paper. Industrial applicability
以上説明した通り、 本発明の用紙パッケージは、 用紙を構成する紙繊維の方向 と用紙パッケージの箱状体を構成する紙繊維の方向とを略同一方向にしているの で、 用紙と用紙パッケージの双方につき湿度の影響を受け難くするとともに、 膨 潤の程度を小さく し、 両者の膨潤特性を同等にすることが可能となる。 これによ り、 用紙の両側端縁と箱状体の側壁内面との間における摩擦力を略一定にして、 箱状体から用紙を一枚ずつ安定的に送り出すことができる。  As described above, in the paper package of the present invention, since the direction of the paper fibers constituting the paper and the direction of the paper fibers constituting the box-shaped body of the paper package are substantially the same, the paper and the paper package Both can be made less susceptible to the effects of humidity, the degree of swelling can be reduced, and the swelling characteristics of both can be made equal. Thereby, the frictional force between both side edges of the paper and the inner surface of the side wall of the box is made substantially constant, and the paper can be stably fed one by one from the box.
また、箱状体にて積層状態で収納される用紙と用紙との間に発生する摩擦力が、 用紙と箱状体の上壁面又は下壁面との間に発生する摩擦力よりも小さく設定する ことが可能である。 この構成により、 積層状態の用紙を一枚ずつ順次送り出すこ とが可能となり、 更に、 用紙の積層数が少なくなつた場合においても、 最後の一 枚まで適正に送り出すことが可能となる。  Further, the frictional force generated between the paper stored in the stacked state in the box-shaped body and the paper is set to be smaller than the frictional force generated between the paper and the upper wall surface or the lower wall surface of the box-shaped body. It is possible. With this configuration, it is possible to sequentially feed the stacked sheets one by one, and even when the number of stacked sheets is reduced, it is possible to feed the last sheet properly.
更に、 箱状体に収納された用紙の紙繊維の方向が、 プリンタの用紙搬送機構に よる用紙搬送方向と略同一方向にすることが可能である。 こうすれば、 用紙搬送 機構により用紙が受ける張力方向と紙繊維の方向とが略同一方向となり、 これに より用紙にカールが発生することを防止することができる。  Further, the direction of the paper fibers of the paper stored in the box-shaped body can be substantially the same as the paper transport direction by the paper transport mechanism of the printer. In this case, the direction of the tension applied to the paper by the paper transport mechanism and the direction of the paper fibers are substantially the same, and thereby curling of the paper can be prevented.
